What three bones comprise the triradiate cartilage?

Answer :

The triradiate cartilage comprises three bones: the ilium, ischium, and pubis, which help form the acetabulum of the pelvic bone.

The triradiate cartilage is a region of cartilage located in the hip joint that ultimately fuses together during growth to form the acetabulum of the pelvic bone. It's comprised of three parts: the ilium, ischium, and pubis. These are the bones that eventually form the socket of the ball-and-socket hip joint.


Cartilage has various functions in the human body, including providing support and maintaining the shape of certain structures, such as the larynx, trachea, and the tip of the nose. In joints, such as the knee, cartilage acts as a cushion between the bones, reducing friction and absorbing shock during movement.
